Chemistry [8.1]
What do we mean if we say a material is synthetic?
It is made by people. It is not naturally occurring.
What is a reactant?
What you put into a chemical reaction
What happens to to kinetic energy when I increase the speed of an object?
It also increases
How do igneous rocks form?
Magma cooling below (intrusive) or above (extrusive) the surface of the earth.
List three consequences of climate change.
Frost free growing season, changing precipitation patterns, droughts and heat waves, hurricanes, arctic ice, ocean acidification, flooding and sea level increase.
What is the difference between an atom and a molecule?
A molecule is made of more than one atom bonded together
What percent of the energy moves up each step of an energy pyramid?
10%
What is the difference between kinetic energy and potential energy?
Kinetic is energy of movement and potential is stored energy
What is one of the processes that deposited copper in Utah?
Magma from mantle, groundwater, tectonic plates breaking crust, sedimentary rock layers, etc...
Are digital or analog signals more reliable for storing data?
digital
What are the 3 subatomic particles that make an atom?
Proton, neutron and electron
List 3 different different places we find carbon.
Oceans, animals, plants, rocks, air, fossil fuels, etc...
What is transferred by a wave?
Energy NOT matter
When magma pushes up through the crust it can go straight up, sideways, or form a big blob. Give the name for ONE of these formations.
Dikes, sills and batholiths
What type of wave are sound waves?
Longitudinal/compression
List 3 things that indicate a chemical reaction happened.
Production of a gas, color change, odor change, temperature change, formation of a new substance
What living things do not do cellular respiration?
None of them!
How can I increase the energy of a wave?
Increase the amplitude (or frequency of a light wave)
Where are you most likely to find mineral deposits around the world?
Along plate boundary lines
Is this equation balanced? P4 + 5O2 → 2P4O10
No, too many phosphorus and oxygen in the products.
What does it mean if a reaction is exothermic?
Produces heat - feels hot
What are the reactants for photosynthesis?
Carbon Dioxide and Water
Which type of wave does not require a medium to travel through?
Electromagnetic (light)
What is the name of the process that forms minerals by dissolving them in hot water and then redepositing them in rocks?
Hydrothermal mineral deposits
What are the reactants for cellular respiration?
Glucose and Oxygen
